Ibis applicationis a division of my applicatikjfi" filed April 26, 1920, Se1ia1 No.'376,504. This invention relates to wheels for vehicles and pairticularly to wheels intended to be used 5 in connection with trucks that are constructed to support and carry ver heavy loads; The invention consists in the particular construction of vehicle Wheels as will be hereinafter V pointed out whereby the Wheel is of simple construction, and at the same time of great strength, as is required for the uses to which it is to be put.

For the purpose of illustration I have, in the accompanying drawing shown and here- 3 in described one form of device embodying my invention.

In the drawing,

Figure 1 is a transverse elevation of a truck provided with wheels which embody the present invention.

Figure 2 is a longitudinal sectional view taken on the line 22 01 Figure 1.

' Referring to the drawing, 1 indicates as an entirety a frame or chassis, which, for illustrative purposes, is shown as provided with an elevating platform 2. My invention is particularly adapted for this type of truck because of the desirability of making the load carrying portion of the frame or chassis, or that part which supports the platforrn 2, relatively 10W; and the necessity of making the wheels that support the load-arrying platform of relatively small diameter'and of very great strength.

7 indicates a pair of relatively small supp0rtin# wheels, which in the illustratel, form of truc construction, are mounted belovthe platform supporting portion of the truck rame- 1. Preferably each of-the wheels 7 'comprises a tubular member 10, extending from side to side of the wheel and serving both as a rim for a tire ll'and as a hub. As shown in Fig. this memher 10 is tubular, that is, it extends for a considerable distance longitudinally of the axle with wl3ich it has a bearing contact at one end While the other end is closedover the end of the mzle. The

side walls of the me nber are relatively thin, thus minimizing the diameter of the member.

The outer surface of the member reccives the tire directly while the inner surface holds the anti friction means. At 12, the inner wall of the annu'1ar inennber is out away to form a. shoulder and scat for the outer raceway of one or more anti-friction bearings 7b, the constructi on beingsuch that the bearings, when positioned against the shoulder, are arranged centrally of the Whel or its tread. 7a indicates an axle' for the Whels 7 it extending into but prefrably not entirely through the hub membersl0 thereof. The axle 7a, at a point near each free and, is reduced in diameter to form a shoulder against Which the inner race of the adjacent anti-friction bearing 772 is seated; 13 indicates a washer and 13a a nut fitting the free end of the axle 7a and engaging the bearing race, preferably the inner race, and axle 7a, respectively, to hold the former in position. The outer end of the hub member 10 may be provided with screw-threads, as shown at 10a, adapted to serve as a sl1itable means for securing an adjustible cap 10' in position against the outer race of the bearings 7?). The cap 10 is proferably fixed in position by suitable locking 1neans 106.

The tubular member 10 is relatively long and of small diameter, and the tire 11 applied thereto approximates width the length of the member 10 and is .preferably formed of solid elastic material, such as vulcanized rubb er. The result is that the wheel member 10 is of great strength and rigidity, so that the antifriction bearings interposed betweeir it and the axle may*be much shorter than is the 35 Wheel hub part 10, as clearly representcd in Fig. 1, the bearings being located midway between theends of the hub and the rinl or tire member 10. This arrangement of parts results in the formation of a truck wheel, particularly adapted for uses forwhich it has been specially designed. The width of tire provided gives the necessary traction and bearing upon the surface over Which the truck passes; the strength and construction of the tubular membersupporting the tire and serving also as a hub gives the necessary strength to bear the loads which the ivheel may be expected to carry, and at the same time permits theuse of antifriction boarings between the wheel and axle of much lcss lengththan the length of the tubular mcmbenl; for, as Will be apparent, a bearing coinc1dcnt in lcngth with that of the hub member is unnecessary and indeed would be undesirable.

It will be seen that the tubular or annular hub and tire member 10 extends in either direction corisiderably beyond the anti-friction bearings for the wheel, forming chambers surrounding the axlc. Thesc chambers are la closcd, the outer one by the cap 10 and the Well known inanner. An opening is provided in the truss member 8 to receive and support a king bolt 9 connectcd at its lower free end to the axle 7a. At 8b'the truss member is formed with an annular reccss and at 9 the bolt is provided with a collar permitting the provision of an anti-friction load bearing 9m. T he lowcr free end of the king bolt 9 is preferably bifurcated, as shown at 9a, and straddles the axle 7a. 9b indicatcs a pin or bolt which extends through openings formed in the bifurcations 9a and axlc 7a and pivotally connects the king bolt 9 and axle 7a together, this form of construction prmitting the whecls 7 to rock about the lower end of the king bolt 9 and accommodate this to the uncvenncss of the floor at all cimes. 7 indicates suitable stops carried by the axle 7a and arranged to be cngaged by sorne suitable part of the king boit to prevent undue inclination of the fram'e 1 and platform 2.

By making the whecls 7 of the type indicated, a Construction is provided which is at once economical, and yct powerful enough to sustain the heavy loads imposed. It is also evident that the wheels may be turned with little efiort. Thc combincd hub and rim member 10 is easily asscmbled and aflords the desired clearance in the limitcd space allowed. Furthermor, it providcs for a tire of ample proportions, as indicated.

A construction of this charaoter is of material advantage in trucks of this class and in similar devices, as will readily be understood by those skillcd in the art to which this invention relates and to such persons many alterations in construction and widely diflering embodimnts and applications of my invention will suggcst themselves without' departing from the spirit thereof and the scope of the claims. My disclosures and the descnption herein are purely illustrative and are not intended to be in any sense limiting.

What I daim is:

In an ndustrial truck construction, the

said member, respectively, removable nieanS engaging the outer end portion of said axle and outer side of the inner race for the outermost set, and removable means en*gaging'the muer wall of sa1d member ad acent its outer end and the outer side of the outer race for the outermost set.

- In testimony whereof', I have hereuntd fixcd my signature. v
